nettle rash

Etymology: AS, netele, nettle; Fr, rasche, scurf
a fine urticarial eruption resulting from skin contact with stinging nettle, a common weed with leaves containing histamine. It is characterized by stinging and itching that lasts from a few minutes to several hours.


(rash) [Fr. rasche, skin eruption]
A general term for any eruption that appears on the skin transiently (as opposed to durable skin lesions such as scars, tattoos, or moles). Synonym: exanthem

Patient care

Assessments are made of the location and characteristics of the lesion: color; size (height and diameter); pattern, whether discrete or coalesced; and any secondary changes (crusting, scaling, lichenification). Associated symptoms such as pruritus or discomfort, temporal elements, history of known allergies, drugs used, and contacts with communicable diseases during prior 2-week period also are assessed. Suspected drugs are discontinued, and the potential communicable disease patient is isolated and assessed. Cool compresses are applied to relieve itching. Topical preparations and dressings are applied and systemic medications administered as prescribed. The patient is instructed to keep hands clean and nails short and even, and to avoid scratching. The patient also is taught about the treatment regimen, its actions, and its side effects and evaluates for desired effects and side effects.

diaper rash

Irritant contact dermatitis as a reaction to friction, maceration, and prolonged contact with urine, feces, soap retained in diapers, and topical preparations. A persistent diaper rash may be colonized by yeast or bacteria. Synonym: diaper dermatitis See: illustration


Treatment is symptomatic. Diapers should be changed frequently. If washable cloth diapers are used, they should be thoroughly washed and rinsed; occlusive plastic pants should not be used over diapers; the perianal and genital areas should be washed with warm water and mild, nonperfumed soap. If these measures and the application of a bland protective agent (such as zinc oxide paste) do not promote healing, then a small amount of 0.5% to 1% topical hydrocortisone cream should be applied to the area after each diaper change until the rash has completely resolved.
